Bone spurs form when your body lays down extra bone tissue in response to ongoing stress, friction, or damage at a joint. They’re essentially bony scars, and while you can’t eliminate every risk factor, the most effective prevention strategies target the root causes: excess joint stress, chronic inflammation, poor biomechanics, and unmanaged injuries.
Why Bone Spurs Form in the First Place
Your body builds bone spurs through a process called osteophytosis. When cartilage wears down or soft tissue near a joint gets damaged, the body tries to stabilize and repair the area by producing new bone. The result is a small, often pointed growth at the edge of a joint or along the spine. This means bone spurs aren’t random. They’re a predictable response to mechanical stress, inflammation, or injury that has gone on long enough for the body to attempt a structural fix.
Understanding this makes prevention straightforward in principle: reduce the stress, control the inflammation, and properly rehabilitate injuries before the body resorts to building extra bone.
Maintain a Healthy Weight
Every pound of body weight translates to roughly two to four pounds of force on your knees when you walk, and even more when you climb stairs or run. That cumulative load accelerates cartilage breakdown, which is the primary trigger for bone spur formation in weight-bearing joints like knees, hips, and the spine.
A large study of nearly 362,000 adults published in Arthritis and Rheumatology found that people with BMIs significantly above the normal range (18.5 to 24.9) had 49% higher rates of osteoarthritis compared to those at a normal weight. Since osteoarthritis is the single most common cause of bone spurs, keeping your weight in a healthy range is one of the most impactful things you can do. Even modest weight loss, on the order of 10 to 15 pounds, meaningfully reduces the mechanical load on vulnerable joints.
Stay Active With Low-Impact Exercise
Regular movement keeps joints lubricated, strengthens the muscles that support them, and maintains the flexibility of surrounding tendons and ligaments. All of this reduces the kind of abnormal stress that triggers bone spur growth. The key is choosing activities that build strength without pounding your joints. Walking, swimming, cycling, and elliptical training are all good options. If you currently run or play high-impact sports, alternating those with low-impact days gives your joints time to recover.
When you do exercise, proper technique matters more than intensity. Warm up before activity, stretch afterward, and wear appropriate footwear. Poor form during repetitive movements is exactly the kind of chronic joint stress that leads to bone spurs over months and years.
Targeted Stretching for Common Problem Areas
Heel spurs, one of the most common types, often develop because tight calf muscles pull on the plantar fascia along the bottom of the foot. Stretching the calves and feet directly addresses this. A few effective options:
- Calf stretch with a band: Sit down and loop a resistance band or towel under the arch of your foot. Pull the top of your foot toward your shin, holding for 15 to 30 seconds. This lengthens the calf muscle and reduces tension on the plantar fascia.
- Towel grabs: Place a small towel on the floor, then curl your toes to grip and lift it. This strengthens the arch muscles and improves flexibility in the foot.
- Wall squat calf raises: With your back flat against a wall and knees bent at 90 degrees, slowly lift both heels off the floor. This builds calf strength while stretching the lower leg.
For spinal bone spurs, focus on core strengthening and flexibility work that supports the muscles along your back. Yoga, Pilates, and basic core exercises reduce the load your vertebrae have to carry on their own.
Fix Your Posture and Workspace Setup
Spinal bone spurs frequently develop in the neck and lower back, and poor posture is a major contributor. Sitting hunched over a desk for hours every day places uneven stress on your vertebrae and spinal discs, exactly the kind of chronic pressure that prompts your body to build extra bone over time.
A few adjustments to your workspace make a real difference. Your upper arms should hang parallel to your spine with elbows bent at 90 degrees when your hands rest on the keyboard. Your lower back needs support: sit with your buttocks pressed against the back of the chair, with a small cushion maintaining a gentle arch in your lower back. Slouching forward shifts strain directly onto your spine and lumbar discs.
Screen height matters too. When you sit with your head facing forward and slowly open your eyes, your gaze should land at the center of your monitor. If you’re looking up or down, your neck compensates with a sustained tilt that stresses the cervical vertebrae. Adjust your monitor or chair height until this lines up. If your feet don’t rest flat on the floor after raising your chair, use a footrest rather than letting your legs dangle, which puts pressure on your thighs and changes your spinal alignment.
Protect Your Feet With Proper Footwear
Heel spurs develop when the plantar fascia or Achilles tendon is repeatedly strained, and shoes play a direct role. Wearing shoes that lack arch support, have flat or worn-out soles, or fit poorly creates the kind of repetitive stress that triggers bone growth on the heel.
Look for shoes with firm arch support, a cushioned sole, and a deep heel cup that cradles and stabilizes your heel. If your favorite shoes are otherwise comfortable but lack support, over-the-counter orthotic insoles with arch support and heel cushioning can fill the gap. These work by distributing weight more evenly across the foot and absorbing shock with each step, reducing the strain on the plantar fascia that leads to heel spurs.
Replace athletic shoes regularly. Most running and walking shoes lose meaningful cushioning after 300 to 500 miles, even if they still look fine on the outside.
Reduce Chronic Inflammation
Inflammation is part of the chain reaction that leads to bone spurs. When a joint stays inflamed for months or years, the ongoing tissue damage signals your body to lay down new bone. Controlling systemic inflammation through diet won’t guarantee you’ll never develop a bone spur, but it reduces one of the key drivers.
The Mediterranean diet is one of the best-studied eating patterns for lowering inflammation. It emphasizes fatty fish like salmon, mackerel, and sardines (rich in omega-3 fatty acids, which are potent inflammation fighters), along with fruits, vegetables, whole grains, nuts, and olive oil. On the other side, certain foods promote inflammation: processed meats like bacon and sausage, deep-fried foods, white bread and pasta, sugar-sweetened drinks, and commercial baked goods. You don’t need to eliminate these entirely, but making them occasional rather than daily choices shifts the balance.
How you cook also matters. Baking, steaming, and quick stir-frying produce fewer inflammatory compounds than deep frying or charring on a grill.
Take Joint Injuries Seriously
One of the most overlooked causes of bone spurs is an old injury that never fully healed. When a ligament tear, tendon strain, or joint sprain doesn’t get proper rehabilitation, the joint may remain slightly unstable or mechanically altered. Your body compensates by reinforcing the area with extra bone. This is why bone spurs often show up years after a sports injury or accident, in exactly the joint that was hurt.
If you injure a joint, complete your full course of physical therapy rather than stopping once the pain subsides. Pain resolves well before the joint has regained full strength and stability. Returning to activity too early, or skipping rehab altogether, leaves the joint vulnerable to the kind of chronic micro-damage that eventually produces bone spurs. For recurring joint pain after an old injury, a physical therapist can assess whether the joint mechanics have shifted and prescribe strengthening exercises to correct the imbalance before bony changes develop.
Recognize Early Warning Signs
Many bone spurs cause no symptoms at all and are only discovered incidentally on an X-ray. But when they do cause problems, the earliest signs tend to be subtle: mild joint stiffness after sitting still for a while, a dull ache at the end of the day, or a slight loss of range of motion in a joint you use heavily. In the spine, you might notice occasional numbness or tingling in an arm or leg if a developing spur starts pressing on a nerve.
These early signals are worth paying attention to, not because a bone spur has necessarily formed, but because they indicate the joint stress and cartilage changes that precede one. Addressing the underlying cause at this stage, whether it’s improving your posture, losing weight, strengthening supporting muscles, or switching to lower-impact exercise, can slow or prevent further progression.
